Solus Linux Installation Issue

Whenever I first install Solus Linux, the installer never adds Solus to the UEFI Boot Menu. Here are the steps to fix that issue:

Boot from your live CD/USB. Connect to the internet, and do the following:

Install efibootmgr: sudo eopkg it efibootmgr

(This paragraph probably isn’t necessary, but I am including it to remember how to clean up the UEFI Boot Menu ūüôā )Run¬†efibootmgr¬†with no arguments. You should see an entry for Linux Boot Manager, which for some reason doesn’t show up in your actual boot menu but does here. There’s a number listed for that entry. Delete it with¬†sudo efibootmgr -b [num] -B

Now you can recreate it. If your EFI partition is /dev/sda1 then do this: sudo efibootmgr -c -d /dev/sda -p 1 -l "\EFI\systemd\systemd-bootx64.efi" -L "Linux Boot Manager"

Fix KDE on NVIDIA Driver

For KDE font/gui size issues after switching to NVIDIA driver, I found the following post:

It’s a nvidia thing lol I had the same issue and never even noticed it until one day I gave the free noveau drivers a try and everything looked way better and smaller. For some reason nvidia sets/forces my DPI to I believe 120, anyways it’s really easy to solve.

Open the nvidia.conf file in your text editor

sudoedit /etc/X11/mhwd.d/nvidia.conf

Then edit or add the option DPI under the screen display sub section and disable UseEdidDpi.

To make things easier here is what I have under my ‚ÄúScreen‚ÄĚ section which now forces the use of 96 for dpi scaling.

Section “Screen”
    Identifier “Screen0”
    Device “Device0”
    Monitor “Monitor0”
    DefaultDepth 24
    SubSection “Display”
        Depth 24
        Option “UseEdidDpi” “False”
        Option “DPI” “96×96”
    EndSubSection
EndSection

I hope this helps you as it did for me.

No Kernel Panic on Shutdown

Okay, so my new computer likes to fail to shutdown in Linux with a kernel panic. Here’s the solution to fix it.

If using Grub:
Add initcall_blacklist=dw_i2c_init_driver to the kernel command line.

Run in the terminal: sudo nano -w /etc/default/grub.
Append blacklist string to the GRUB_CMDLINE_LINUX_DEFAULT=”‚Ķ initcall_blacklist=dw_i2c_init_driver”.
Save the file.
For Debian:  sudo update-grub.
For Fedora:  grub2-mkconfig -o /boot/efi/EFI/fedora/grub.cfg
For Arch: grub-mkconfig -o /boot/grub/grub.cfg

Reboot and test!

If using goofiboot (Solus):
sudo nano -w /etc/kernel/cmdline
Insert the following line: initcall_blacklist=dw_i2c_init_driver
Save the file.
sudo clr-boot-manager update
Reboot and test!

If using systemd-boot (Pop_OS):
sudo nano -w /etc/kernelstub/configuration
Insert the following line: “initcall_blacklist=dw_i2c_init_driver”,
Save the file.
sudo kernelstub
Reboot and test!

Learning QGIS 2.0

I have received a review ebook of Learning QGIS 2.0 by Anita Graser.  It is distributed by Packt Publishing and can be obtained from here.  I am currently working my way through the book and will be reviewing it soon. Thank you Packt Publishing for the opportunity!

Ubuntu 12.10 Launched!

Ubuntu is so lucky… It has a birthday every six months! ¬†Happy 12.10 birthday Ubuntu! ¬†I’ve got it installed and running on my computer, but I really haven’t gotten much chance to play around with it as I’ve been at work or grocery shopping. ¬†I have managed to find a nice, little bug in the proprietary nvidia graphics driver installer. ¬†Other than that, I haven’t really done a whole lot with it. ¬†Patience, patience…

Ubuntu 12.10 & Windows 8

Later this month, both of the operating systems that I use will release upgraded versions. ¬†I use both Windows 7 and Ubuntu 12.04 right now. ¬†Windows 8 will be coming out on October 26th, and Ubuntu 12.10 is scheduled to come out October 18th. ¬†I’m getting excited. ¬†I’m looking forward to Ubuntu 12.10, though I’m a little¬†leary¬†about Windows 8. ¬†I’m not sure I’m going to like it, but I have been playing with Windows Server 2012 in a Virtual Machine. ¬†So far, it seems okay. ¬†Maybe I’ll download the Windows 8 evaluation to use in a VM as well…

Debian

Debian Logo

I’ve decided to switch from Ubuntu to Debian Unstable. ¬†A couple of years back I used to use Debian exclusively, but I got a little bored with it because it always worked! ¬†Well, I’m kind of tired of Ubuntu’s graphical issues and the strange decisions Canonical makes (though I do kind of like Unity). ¬†I’ve made the switch to Debian and have both Gnome Shell and KDE installed. ¬†I tend to use Gnome Shell more, and am actually starting to like it. ¬†There are no graphical problems like Unity had (Compiz always gave me problems, even before Unity). ¬†I think I’m pretty happy with the switch!

Ubuntu 11.10

I’ve been using Ubuntu 11.10 for a while now. ¬†So far it seems okay. ¬†It has a lot of improvements over 11.04. ¬†The main problem that I have is that sometimes, especially when switching users, the system fails to switch to the GUI properly. ¬†It normally isn’t a problem for me, as I know most of the shortcuts like Ctrl-Alt-F8 and stuff, but it isn’t good for my wife. ¬†I hope that problem gets taken care of in 12.04.
